In the following example, AIX system has 2 disks in the rootvg with mirrored lv except ibmDIRlv . The boolist contains both hdisk0 and hdisk1. There are no other logical volumes in rootvg other than the AIX systemlogical volumes. hdisk1 has failed and need replacing, both hdisk0 and hdisk1 are in “Hot Swap” carriers and therefore the machine does not need shutting down. In the below procedure from steps 9 to step 15 are only applicable to Internal disk and are not applicable to SAN LUNs.

Pre Requisite: Make a note of the slot disk number for replacing disk using lscfg -vl hdisk1

Step1:- if hdisk0 and hdisk1 are not similar migrate lv’s those are not in hdisk0. Here hdisk0 containing all hdisk1 LVs except ibmDIRlv. To move physical partitions in logical volume ibmDIRlv from hdisk1 to hdisk0, enter
